Enabling RT::Mason causes apache error


    I have a server with a working RT on it (version 3.4.5).  One
    a separate virtual domain, I added a 3.6.6 RT that is
    completely separate (different directory, db, etc).

    I got the thing set up as far as getting to the point of
    doing the apache configs.  I am getting this message when I go
    to the newer RT:

Not Found
The requested URL / was not found on this server.

    If I comment out these two lines in my apache configs, I get
    the "You're Almost There!" message:

SetHandler perl-script
PerlHandler RT::Mason

    But with those lines in place, I get the 404 error above.

    I am not getting any useful information from my apache error
    and access logs.  There is nothing in the var/log directory in
    my RT install directory in /opt.

    Has anyone seen anything like this ?  Is there some sort of
    debug flag I can turn on somewhere to get me more information

    If I cannot get this fixed quickly, I will try simply copying
    the 3.4.5 RT that works on this machine . . . I would like to
    use the latest version if possible, however.
